portable way to tell what Popen will call

[Brendan Miller]

I need a portable way to tell what subprocess.Popen will call.

For instance on unix systems, Popen will work for files flagged with the
executable bit, whereas on windows Popen will work on files ending the in
..exe extension (and I don't think anything else). Is there a portable way
to check what Popen will work on without actually execute it? Do I have to
write a bunch of platform specific code here?

Thanks,
Brendan

Actually, if you pass the use_shell = 1 argument to Popen, it will
launch the process using a shell - that is, what you expect to work in
a shell (and consequently os.system()) will work.

Unfortunately, you'll probably need to write platform specific kludges
for this.
